I (used to) work in academic IT and I hate articles like this. People would assume there is a serious problem, turn off a bunch of services, run a bunch of random-ass shell scripts, and then forget that they'd done all that and at some random point in the future discover that some feature wasn't working, and blame me.

No-one should run these shell scripts unless they're 100% sure that they know what they're doing. The problem lies in the fact that anyone can run shell scripts which can break the OS or make the OS work.

Unfortunately, there's a very thin line between making it work and making it break.

I swear I really wish there were a way to output an entire OS's "diff" from default settings. Every preference pane, every terminal setting, every changed system file. So that you could both discover, in cases like this, what's changed -- but also simply so you could export your settings in a space-efficient way and (selectively) re-import on a new OS install.

The amount of changes that your OS goes through (downloading applications, applications creating files, applications changing files) is too much to update on a diff file.

Although, for the major changes I feel the major OS's should add the ".diff" file called updates.diff and describe the major updates in your laptop.

This should also happen each update, we need to know what updates are going to be installed, and what is the purpose of doing this?

This reminds me of the general idea behind Tripwire[1] for macOS. I last looked into it back in 2005 (we went with other approaches), so it may have changed since then, but it monitors for changes, and allow you to revert them or deploy them to other computer (as in a lab, etc).

Their actual solution for disabling AWDL is running this script in the background: while true; do if ifconfig awdl0 |grep -q " That just checks the awld0 interface every second and turns it off if it's on. Apple really doesn't offer any other way to disable awdl? Note that setting AirDrop to "No One" doesn't fully disable awdl. It's used for other things like screen sharing, AirPlay, bonjour device/service discovery,…

Came here to say this. It's unfortunately not a new problem. I use Shadow Tech on my M1 Macbook to play windows games, and this has been bugging me ever since. The irony is that this problem is non-existent on old Macbook pros.

Here's an example of SOF solution: https://apple.stackexchange.com/a/413735

But if you search around the internet you will see different solutions proposed for it, none worked for me except for this script.

This popping up on HN gives me hope that next versions give you at least a tool to disable Wifi direct.

I'm glad Meter published this post as I've been fighting this issue for the last couple of weeks and wasn't able to find much information on the root cause.

I started getting packet loss recently, and after being unable to find the cause, I tried upgrading my router. That somehow made things worse -- rather than intermittent packet loss, it would get into a completely unavailable state and not recover. I couldn't even switch to other networks without restarting wifi.

This affected multiple M1 machines and an iPhone, so I was quite sure it was an Apple issue, but wasn't able to find the root-cause. After some limited testing, I'm pretty sure this issue caused both my intermittent packet loss as well as complete downtime.

I don't know why people are dismissing this as non-viable or complex. For example, a typical Windows deployment is 15-20GB after being extracted from an ISO image that's essentially static. There's monthly updates, which are also monolithic multi-GB patches that wholesale replace system files. This is basically like a Docker image, but with the Kernel and drivers included in the base layer... .. but without any of th…

don't forget all the cargo-cult of people stumbling on this article with unrelated wifi issues!

Including all the tech-savvy computer people with decades of experience, who figure the modern hardware and software has so many complex interactions that it's often better to try any plausibly looking solutions first, and only then figure out why it worked (or revert it if it didn't).

Not a full OS-diff, but there is a way to dump all the packages installed on a machine:

    $ mpm --output-format json installed > installed.json

With regular snapshots you can at least eliminate new installed software as the root cause of an issue. Doesn't solve the issue with preferences though.
